Weaknesses: In starter Trevor Siemian and Lynch, Broncos have two QBs who have never thrown NFL pass. O-line is banged up with Ty Sambrailo, Darrion Weems and James Ferentz missing significant camp time with injuries. D-line was depleted by season-ending ACL injury to Vance Walker, Jackson’s replacement.

Expectations: Broncos are gearing for Super Bowl repeat behind Siemian, whose only snap as rookie was kneel-down at Pittsburgh in December. Manning’s successor won’t have to carry team’s high expectations alone thanks to Miller and rest of Denver’s dazzling defense that has chance to be even better in 2016, and skill players that surround him on offense.
